Question

The Tip Of The Seconds’ Hand Of A Clock Is Colored Red. Which Of The Following Types Of Motion Will Be Exhibited By The Red Colored Tip Of The Seconds’ Hand Of This Clock?

Answer 1

Uniform circular motion will be exhibited by the red coloured tip of the seconds' hand of this clock.

Explanation:

• The motion of a body travelling with constant speed along a circular path is called Uniform Circular Motion. In this case, the speed is constant but the velocity varies.

• If a body is moving in a circle, it must have certain acceleration acting towards the centre which is causing it to move around the centre.  

• As this acceleration is perpendicular to the velocity of the body at every single instant, it is only altering the direction of velocity and not magnitude and that is why the motion is uniform circular motion.

• The attached diagram shows uniform circular motion.

Answer 2

Answer:

Periodic motion and circular motion is the answer.
